Hi, I recently tried using the edid feature in QEMU for my Mac OS 10.8 guest like this: -device VGA,edid=on,xres=1280,yres=800. When the guest operating system loaded there were no additional options available in the Display settings. Would you know what is wrong?
Thank you.

Probably macos just doesn't read the edid block ...
take care,

You need increase VGA memory size with `vgamem_mb=64`.

Hi,
Probably it was due to the low default vbe size.
Adding a `vgamem_mb=64` to the option list would be suffice.
Best regards

Thanks for the help. The option unfortunately did not work.
